What Are the Most Common Problems With Richmond Water Heaters?

You will surely get the best quality when you own a Richmond water heater. 

Unfortunately, however, no appliance goes without breaking down, sometimes due to negligence or poor appliance maintenance.

And the unannounced breakdowns count as an important reason you are supposed to have adequate knowledge of the workings and operation of your Richmond water heater.

Some common problems with Richmond water heaters include the following.

#1. Failure of Main Burner to Stay Lit

The Richmond water heaters consist of an explosion shut-off tool that spontaneously closes the unit anytime it detects any form of explosive gas or when the air channel gets obstructed.

Anytime the explosion shut-off tool gets tripped or faulty, it turns off the unit, causing the main burner not to stay lit.

It will help if you call on an expert because handling the shut-off tool requires knowledgeable personnel.

#2. Relief Valve Making Popping Noise  

Over time thermal expansion causes a high-pressure build-up which produces the popping noise by the relief valve.

In such a situation, replacing the relief valve won’t solve the issue, and you must call on an expert to check and resolve the problem.

Once you observe that whizzing sound, you should turn off your heater and call for service.

#3. Water Is Too Hot

Once you notice your Richmond water heater giving off overly hot water, check out the thermostat.

In most cases, you have set the thermostat unduly high, or your heater has a faulty gas control valve.

You can quickly check and adjust the temperature settings of your heater. Also, check that the control valve is not faulty, and do well to replace it if damaged.

#4. Failure to Light the Main Burner

Your heater’s main burner will fail to light if the air in the gas pipe or the exhaust line gets obstructed.

Also, an inadequate gas control or obstructed pressure switch hose will cause the main burner of your heater not to light.

Ensure no air is in the gas pipe, and ensure the exhaust line or pressure switch hose is not obstructed. Clear any form of obstruction and try lighting your gas again.

#5. Yellow Soot

A build-up of scale on your burner and constrained combustion inlet spaces will cause yellow soot on your Richmond water heater.

Thoroughly clean and remove any dirt or debris from your appliance and ensure you install your heater where there is adequate ventilation.

Why Does My Richmond Water Heater Keep Shutting Off?

Dealing with a water heater that keeps shutting off can be a frustrating experience. 

And that is why Richmond recommends constantly servicing your water heater to ensure it is in perfect working condition.

Many factors will cause your water to keep shutting off, and some of the factors include the following.

#1. Dirty Pilot Burner 

A dirty or clogged pilot burner will prevent your gas burner from heating. 

Once the pilot burner gets clogged with dirt, the gas burner will need more gas to generate a steady flame.

It would help if you constantly clean the pilot orifice of your heater to prevent dirt obstruction.

#2. Clogged Air Inlet

Richmond water heaters have air inlets needed for the gas to burn. When the inlet gets blocked, your heater gets less air for proper gas burning.

#3. A Faulty Gas Valve 

The gas valve plays a crucial role in providing gas to the heater for heating.

A damaged component of the valve will cause a fluctuation in the performance of your water heater. 

As such, your appliance will shut off frequently due to an inadequate gas supply. Generally, once there is insufficient fuel reaching your water heater, it will randomly shut off.

#4. Dirty Thermopile 

A dirty or broken thermopile will cause your water heater to shut off.

The thermopile activates the controls on your water heater by generating energy that powers the electronics in the gas regulators.

However, dirt will interfere with the response of the thermopile to the pilot light. And even when the pilot light remains lit, the heater will still shut down.

What Are the Richmond Water Heater Error Codes?

Whenever a particular component on your water heater is faulty, the appliance displays an error code indicating a particular problem that needs fixing.

Some of the most common error code messages displayed by Richmond water heaters include the following.

#1. Error Code 00

When there is continuous combustion, your heater will display the error 00 messages.

To clear the error, you must turn off all your hot water faucets and reset the unit. Also, close or take out the circulation pumps.

#2. Error Code 02

Your heater displays code 02 when there is no burner performance during freeze safety mode.

It would help to call an expert to service and fix the error.

#3. Error Code 03

Richmond water heaters display error code 03 when a power supply breaks during a bath fill.

You must close all hot water faucets and reset your heater to fix the error.

#4. Error Code 05

Whenever there is poor combustion, the water heater displays the error 05.

The best way to fix error code 05 is to clean the combustion air fan and the air channel filter. Ensure there is adequate ventilation.

#5. Error Code 11

The error code 11 is due to a failed ignition.

To fix the error, ensure your heater has a constant gas supply. And ensure the pressure is sufficient to run the heater.  

#6. Error Code 12

Your Richmond heater will display the error code 12 message when there is a low flame signal.

Check and ensure your heater has enough gas for heating. Then modify manifold pressure if necessary.

#7. Error code 13

When your heater gets a low fuel supply pressure, and a pilot tube erodes, error code 13 will pop up. Modify the gas pressure and ensure there is sufficient ventilation.

#8. Error Code 45

Once the pressure switch gets stuck on open, your heater will display the error code 45 message. Ensure the pressure switch is not damaged.

Also, make sure there is adequate ventilation and unclog any blocked exhaust.

#9. Error Code 47

When a combustible vapor sensor is locked out, the heater displays the error code 47 message. Reset the control and check the presence of any combustible gases.
